Title: Improvements relating to fine adjustment mechanism for rotatable members of electric tuning devices
IPC: H03J1/14
Filed: 1928-04-26
Abstract: 291,728. British Thomson-Houston Co., Ltd., (Assignees of Tar, D. R. de). June 6, 1927, [Convention date]. Wireless tuning-apparatus, adjustment and indicating devices for.-Fine-adjustment devices for the rotatable members of tuning devices, such as condensers in radio apparatus, comprise a pulley 5 attached to the rotatable member and having fixed to and lying around its circumference a flexible cables 8 the ends of which pass round a control shaft 9 and simultaneously wind and unwind when the shaft 9 is rotated. To prevent slackening of the cable, its length between the points of tangency on the shaft 9 remains approximately constant, these points moving at the same rate in the same direction when the shaft 9 is rotated. When these points are at the centre of their travel, the parts of the cable on opposite sides of the pulley 5 make equal angles with, and on opposite sides of the normal between two parallel planes containing the shaft 9 and the shaft 2 of the pulley 5. Grooved drums 6, 7 on the shaft 9 receive the ends of the cable 8. The cable is received in two grooves near the edges of the pulley 5 and passes from one groove to the other through apertures 12, 13 to prevent slip, the tension being adjusted by a screw-adjusted lug 14 passing over the cable. The shaft 2 may carry the motor of a number of condensers, the stators 3 being held in a support 4. A counterweight 20 and stops limiting the movement of the motors are provided. The pulley 5 carries a cylinder 16 provided with an indicating sheet 17 visible through an opening in an enclosing casing. The cable 8 may be of metal. The shafts 2, 9 may be at right angles.

The head 5, Fig. 2, is mounted on a gear box 2 supported by a standard 1. and is furnished with two radial shafts 16, 17, the shaft 17 being shown in operative position. The head is provided with a hollow shaft, Fig. 3, carried in bearings 3 in the gear box. and the radial shafts 16, 17 are driven by worm gearing 22 from short shafts 20, Fig. 4, either of which, on the adjustment of the head, can be coupled through a dog clutch 24, 25 to a shaft 7 in the gear box driven from the main shaft 6 through change gears 8. Adjustment of the head is effected by operating a hand-wheel 13 working on a fixed threaded rod 10, thus moving the head longitudinally of the shaft and disengaging it from a projecting sleeve 26. The' head may then be rotated in the bearings 4 to bring the appropriate mixing shaft into operative position, and the hand wheel 13 turned to move the head into re-engagement with the projection 26. As shown, the shaft 17 is furnished with subsidiary shafts driven by planetary grating, while the shaft 16 is provided with a crank disc, as in Specification 253,474.

Title: Manufacture of unsaturated aldehydes
IPC: C07C45/59
Filed: 1942-09-04
Abstract: a  : b -Unsaturated aldehydes are prepared by subjecting an a -keto-g -lactone to thermal decomposition.  In place of the a -keto-g -lactone, there may be used a derivative in which the oxygen atom of the a -keto group is replaced by a group which is capable on hydrolysis of forming the a -keto group or which is capable upon thermal splitting and hydrolysis of forming the aldehyde group.  This may, if desired, be carried out in the presence of a catalyst and/or a solvent.  Materials suitable as catalysts include copper or other metals, particularly in powder form, and other surface active materials such as fuller's earth and activated charcoal.  It is preferred that the reaction should take place in the absence of oxygen, and also under reduced pressures.  In examples: (1), the lactone of 3-oxy-cholestone-2-oxalylic acid is distilled in a water pump vacuum.  The distillate is dissolved in hexane and purified by chromatographic adsorption to give D 2-2-formyl-cholestenone; (2) hexahydro-cumaranedione is distilled in a current of carbon dioxide at ordinary pressure to form D 1-tetrahydrobenzaldehyde; (3) 7-methyl-hexahydro-cumaranedione is heated under reflux in a current of nitrogen until the evolution of carbon dioxide ceases. The residue is distilled to give tetrahydro-meta-tolylaldehyde; (4) 2 : 3-diphenyl-4 : 5 - dioxo - tetrahydroferane is heated in quinoline with the addition of copper powder to form a -phenyl-cinnamaldehyde. The a -keto-g -lactones which may also be described as 2 : 3-dioxy-tetrahydrofuranes may be prepared by the condensation of a -keto acids with carbonyl compounds, or by condensing a ketone with an oxalic ester to produce first an unsaturated a -keto-g -lactone which is then hydrogenated.  Hexahydro-cumaranedione is prepared by heating cyclohexanone-2-oxalylic acid with acetic anhydride and then hydrogenating the product.  7-Methyl-hexahydro-cumaranedione is prepared by the hydrogenation and saponification of 7-methyl-4 : 5 : 6 : 9-tetrahydro-cumaranedione-3-enol acetate.

Abstract: 955,206. Projectile fuzes. DIRECTOR GENERAL OF FORSVARETS FABRIKSSTYRELSE. April 2, 1962 [Oct. 31, 1961], No. 12640/62. Heading F3A. A projectile impact-operated fuze comprises an annular casing 3 which may be of hardened aluminium alloy and which contains a primer charge 2 such as lead azide plus tetrazene and an auxiliary charge 4 of an explosive such as tetryl. The casing 3 protrudes in front of fuze body 8 and is closed at its rear by an apertured plug 5, the latter being held within the forward end of a guide bushing 24. A booster 11, 21 having charges 10, 20 and joined together by a bushing 14 is contained within the guide bushing 24, the portion 11 having a solid metal part 7 which enters the aperture in plug 5. Externally of the guide bushing 24 is a sleeve 12 which is releasably attached by a looking device 6 to a protective cover 1. Fig. 1 shows the fuze in the unarmed position with balls 16, located in slots 13 of guide bushing 24 and apertures 15 of sleeve 12, pressed against a locking sleeve 18 by a spring 22 via a conical shoulder 17. On launching the projectile, set-back of the booster 11, 21 and of locking sleeve 18 against the action of a friction spring 19 causes the balls to move radially inwardly adjacent the top of bushing 14. On cessation of positive acceleration, spring 22 urges forward the unit comprising booster 11, 21, sleeve 12 and cover 1, the balls 16 still protruding sufficiently into the apertures 15 to move the sleeve 12 forward. When armed, the charge 10 is encircled by auxiliary charge 4 and cover 1 is thrown clear of the projectile after being released by movement of locking device 6 forward of fuze body 8. The guide bushing 24 together with casing 3 is free to move forwardly until engagement between a shoulder 23 with locking sleeve 18 occurs. In another embodiment the outer wall of casing 3 is bent over to form a double thickness inner wall at the forward part of charge 2 and a modification of this embodiment is shown in Fig. 4 where a closure 31 is also provided. In this form forward movement of booster 11, 21 is braked due to compression of entrapped air.
